Abstract

The invention discloses a preparation method of fluorine-free jade-imitated tableware. The preparation method comprises the following steps: proportioning materials, smelting raw materials, pressing and molding, carrying out annealing treatment and carrying out air cooling and toughening, wherein the adopted materials comprise yellow phosphorus slag powder, aluminum limestone, aluminum oxide, quartz sand, barium oxide, lithium oxide, phosphorus pentoxide, zirconium oxide, a clarifying agent and silicon dioxide. The fluorine-free jade-imitated tableware produced by the method does not contain fluorine, and the environment protection aim is realized.

Description

technical field [0001] The invention relates to the technical field of tableware manufacturing, in particular to a method for preparing fluorine-free imitation jade tableware. Background technique [0002] Imitation jade tableware is tableware made of opaque glass, which has greater advantages compared with ceramic tableware and transparent tempered glass tableware. The imitation jade tableware has a delicate hand feel, a realistic jade feel, and the color is milky white and bright, which has changed the shortcomings of the traditional glass color and is not popular enough, and has wider applicability; the imitation jade tableware is hard, corrosion-resistant, heat-resistant, and impact-resistant. Strong, very suitable for microwave ovens; imitation jade tableware is made of opaque glass, which has a wide range of sources, low production cost, simple production process, waste products generated during the production process and fragments generated during use can be reused, w...
